PUMP.

Specification of Letters Patent.

Patented May 30, 1916.

Application led March 29, 1912. Serial No. 687,291.

To all whom t may concern Be it known that I, .FRANK R. CHILDREN,

a citizen of the United States, residing in,

Council Bluffs, in the county of Pottawattamie and State of Iowa, haveinvented a new and useful Improvement in Pumps, of which the followingis a specification.

This invention relates to improvements in pumps.

The object of the invention isto provide a pump, such, for instance, asis used in transferring oils from a barrel, and which is adapted to beattached directly to the original barrel.

Another object of the invention is to so arrange and construct thedelivery spout of the pump as to prevent loss of 011 or other materialdue to dripping.

Another object of the invention is to prolvide a structure comprised offew parts, simple and compact in arrangement, and one which may becheaply manufactured.

My invention furthermore consists in the novel construction of parts anddevices and in the novel combinations of parts and devices herein shownand described and more particularly specified in the claim.

In the drawing forming a part of this specification, Figure 1 is avertical, sectional View, showing my improved pump attached to a barrel,the latter being shown as broken in order to get the same on the sheet.Fig. 2 is a partial, detail, vertical section, taken on the line 2 2 ofFig. 1. Fig. 3 is a horizontal sectional view, taken on the line 3-3 ofFig. 1, and Fig. 4 is a transverse, horizontal section, taken on theline 4 4 of Fig. 1.

In the drawing, I have shown the pump as comprising a cylinder or casingwithin which slides the piston 11, the latter comprising preferably apair of leather washers 12 secured in place by washers 13 screwed on thelower end of a rack member 14. The rack member 14 is adapted to bereciprocated up and down by means of a pinion 15 mounted on a shaft 16supported in brackets 17 at the upper end of the casing or cylinder 10,the shaft 16 being provided with a crank arm 18, whereby the latter maybe manually operated. Screwed into the bottom of the piston or cylinder10 and communicating with the interior of the latter is a T-pipe 19having screwed thereinto on one side the elbow 20 and at the bottomthereof the inlet pipe 21. Secured in the upper end of the inlet pipe 21is a valve seat 22, preferably of soft metal and coperating with a ballvalve 23, the latter being limited in its upward movement by a pin 24secured in the T- member 19. The inlet pipe 21 is provided with asflidable sleeve 25 adapted to be ad- Justably' retained in position onthe pipe by means of .ifi set screw 26. The sleeve 25 is exteriorlythreaded and is adapted to fit an interiorly threaded bushing 46, suchas is ordlnarily provided on original barrels containing oil. I haveshown the sleeve 25 as threaded into v:such a bushing in the top 27 of abarrel or inclosed receptacle 28 adapted for shipping oils or otherliquids. Threaded into the upturned end of the elbow`20 is a shortnipple 29, the same being provided with a valve seat, preferably ofsoftmetal 30 and in which is adapted to be seated a ball valve 31, thelatter being limited in its upward movement by a pin 32 secured in thelower end of a vertically extending spout 33, the latterbeing attachedto the nipple 29 by means of a coupling 34. The spout 33 is providedwith a short, downturned end 35, and at the joint or bend in the spoutformed between the main portion of the'spout and the downturned end 35onthe interior thereof is an upwardly extending ledge or projection 36.

With this structure it will be apparent that waste of oil or otherliquid due to dripping will be prevented by this ledge 36, since the oilor liquid remaining in the tube, after the downward movement of thepiston l1 has ceased, will fall back down the main portion of the spout33. By making my improved pump in such a way that the same may bereadily secured'to original barrels containing oils or other liquids, Ialso prevent the waste of oil or liquid due to transferring the oil fromthe original containers to a storage tank in the manner which hasheretofore been customary. Another advantage of my construction residesin the fact that the pump is readily interchangeable from one ori inalbarrel to another.

The pump is a justable with respect to The pump is accurately adjustableto bring the spout over a desired delivery station rangement permits thechanging of the position of the spout in a horizontal plane withoutaffecting the pipe adjustment.

By using the original receptacle for stor-v age purposes, the contentsare kept cleaner than by the old method where the oil or other liquid istransferred from the shipping eceptacle to a storage tank, andfurthermore danger of loss from leaky faucets or valves and theconsequent danger from fire where inflammable liquids are used is'avoidedby my method of using the original container in connection withthe pump. With my improved form of pump, it will be obvious, also thatif there is any of the oil or other liquid spilled in the transferringof the liquid from the receptacle to the measuringy can, the same may beeasily cleaned up and there will be no danger of y A pump having thedrippings or spilled contents soaking into the Hoor.

I have shown one form of my inventio but it will be understood that thesame i merely illustrative and that many change and vvariations may bemade -without de parting from the spirit of the invention, and all suchchanges and variations are contemplated as fall within the scope of theappended claim.

I claim an upwardly extending outlet spout or pipe provided with a down`turned vertically extending nozzle at the end thereof and being providedfurther with an upwardly e'xtendlng sharp ledge projecting from theintersectlon of said pipe with said spout, Said ledge forming arestricted passageway at the intersection of the main portion of saidpipe and the down-turned nozzle, theouter face of said ledge beingdisposed substantially .in the plane of the adjacent face of said nozzlewhereby to provide means for suddenly stopping the flow of liquidthrough the spout without subsequent drip or waste.
